That sucks. Next time that happens use a small 3 or 4 pronged puller like they use for pulling pulleys or steering wheels off of cars. What really sucks is just last night I sold 2 cranks like your describing. One in a 165mm length and one in a 170mm length.

Yeah - went over to my buddies house because he said he had a crank puller but he didn't have one that was a proper fit I guess so out came the hacksaw. So one just-missed-em, and three shouldas. Ouch. Hammering didn't work; that came before the hacksaw. Lucky I don't need the crankset at the moment so I'll just patiently check the LBS if no one comes to the rescue in the next couple of days.
